Core target expression and clinical analysis through the GEPIA database showed that the expressions of EP300 (Fig. 6C), HSP90AA1 (Fig. 6E), HSP90AB1 (Fig. 6F), SRC (Fig. 6H) and TP53 (Fig. 6I) were upregulated in GC tissues compared to non-cancerous tissues (Fig. 6). This evidence concerns the gene HSP90AB1 and gastric cancer.
